We are proud to introduce the World's first real action paintball marker that is identical to the legendary M4 rifle used by SWAT Teams, Special Operation Groups, and the U.S. Military. The M4 carbine, the U.S. Military's primary weapon of choice is known for its solid construction, durability, and sustained reliability. You can have the same dependable weapon in a paintball marker, the RAP4! This marker was designed to replicate the look, feel, and action of the real M4. With features that mimic the M4, such as shell ejection after every shot, magazine fed paintballs, and a collapsible or solid stock which houses a Co2 cylinder. The RAP4 shoots .40 or .43 caliber paintballs which are encased in plastic (biodegradable) or alloy shells. With the latest improvements to the RAP4 line much better accuracy, range, and precision is achieved.
